Seasonal forests cover about 15% of the Brazilian Savannah and are among the most degraded and fragmented vegetation types in this biome. This study aimed to provide an overview of the current knowledge on these forests and disseminate information that can contribute to the amplification and deepening of previous studies. It shows that previous studies have already explained a large amount of questions raised by earlier researchers, but that the knowledge on some important aspects still remains incomplete. The anthropogenic activities reduction in the remaining areas, as well as the restoration of connectivity between fragments and the development of sustainable exploitation methods, were pointed out as major challenges to be faced by people involved in the study and management of these forests.
